Even though the West meteorite, as it is being called, is a chondrite, which is the most common type of stony meteorite, Stimpson said he is thrilled to have it because it's something new for his museum.

Apophis is fairly well characterized and has a very close approach on 13-Apr-2029, although it may not be an LL chondrite after all, and may therefore have a different albedo, diameter (currently 270m), and mass (currently 27 Mt - million tons).

Of course, a common carbonaceous chondrite might contain 25% nickel-iron mostly in the form of metal grains, 10% or more water, and several percent carbon plus everything else needed for life in space.

However, there is a good chance that we'll need to ship large amounts of ammonia to the habitat, at least until we can capture the resources of a comet, extinct comet, or carbonaceous chondrite asteroid which should have nitrogen in abundance.
